Co-existence and interaction between myxomycetes and other organisms in shared niches
Dudka, Irina O. | Romanenko, Katerina O.
The ecology of myxomycetes co-existing with the Latridiidae (Coleoptera), bryophytes and ascomycetous, basidiomycetous and anamorphic fungi were studied in Crimea and at different locations on the left bank of Ukraine. Results from the left bank indicate that the Latridiidae feed on myxomycetes. Colonies of the most common 13 myxomycete species (which included Stemonitis axifera (Bull.) Macbr., S. fusca Roth, S. splendens Rost., Fuligo septica (L.) Wigg. and Mucilago crustacea Wigg.) were inhabited by 5 species of the Latridiidae. Myxomycete spores were present in guts of 19 of the 25 beetle specimens investigated. Beetles Latridius hirtus, Enicmus rugosus and E fungicola seem to be obligate myxomycete feeders, while Corticarina truncatella was clearly facultative. 13 species of myxomycetes were recorded on 9 species of moss and 3 species of liverwort developing on decaying wood or bark in the Crimean Nature Reserve. Relations between myxomycetes and bryophytes on woody substrata are spatial rather than trophic, and are possibly regulated by specific microclimatic conditions inside bryophyte thallomes. 69 species of myxomycetes were found co-existing with 36 species of ascomycetes, 21 species of basidiomycetes and 9 species of anamorphic fungi in the Crimean Nature Reserve. Associations formed by myxomycetes and fungi on different woody substrata are analyzed.
